5.4. Poliklinova belt

Poliklinova the belt carries out the drive of the generator, the pump of the amplifier of steering, the fan of a radiator, the compressor of the conditioner and the water pump depending on modification of the engine.

Removal
Switch off ignition and disconnect a wire of "weight" from the rechargeable battery.

Preventions
It is forbidden to open a contour of coolant of the air conditioning system.
Before removal by chalk, a marker or paint note the direction of rotation of a poliklinovy belt. If at installation of the poliklinovy belt which was in the use, poliklinovy the belt rotates in other party, it will lead to its destruction. Make sure that poliklinovy the belt is correctly located on pulleys.

Notes

Fig. 3.3-22. The units put in action by a poliklinovy belt: 1 – poliklinovy belt; 2 – adjusting plug; 3 – bolt, 22 N · m; 4 – generator; 5 – bolt, 45 N · m; 6 – bolt, 22 N · m; 7 – generator arm; 8 – bolt, 10 N · m; 9 – bolt, 22 N · m; 10 – protective cover;
11 – bolt, 22 N · m; 12 – the directing roller; 13 – the directing roller; 14 – cap; 15 – bolt of M10, 45 N · m; 16 – bolt of M6, 10 N · m; 17 – a radiator fan arm with the viscous coupling; 18 – bolt of M8, 22 N · m; 19 – fan pulley; 20 – laying; 21 – arm; 22 – bolt, 22 N · m; 23 – pump of the amplifier of steering; 24 – bolt, 22 N · m; 25 – pulley of the pump of the amplifier of steering; 26 – bolt, 22 N · m; 27 – a quencher of fluctuations with a pulley of a poliklinovy belt; 28 – bolt, 22 N · m


For simplification of access to a tension roller of a gear belt it is necessary to remove a cap of 14 (fig. 3.3-22).
At installation it is necessary to use new laying 20.

Face key turn counterclockwise the mechanism of a tension of the main poliklinovy belt, thereby having weakened a belt tension, fix the tension mechanism in this situation a pin (fig. 3.3-29) and take off a belt.

Installation
Installation is carried out to the sequences, the return to removal, taking into account the following.

Fig. 3.3-30. An arrangement of a poliklinovy belt on pulleys of the diesel engine



Establish poliklinovy a belt at first on a pulley of a bent shaft, then on single pulleys and in the last turn on a pulley of a tension roller (fig. 3.3-30).
Face key turn counterclockwise the mechanism of a tension of a poliklinovy belt, take a pin and release a key therefore the belt will stretch (fig. 33-29).
Establish poliklinovy a conditioner compressor drive belt.
